Back when I first started to work as a certified HVAC repair tech things were much more straight-forward, however the only people that had air conditioner units were the rich families in town plus they all had the same exact air conditioner units.
These units were constantly undoubtedly straight-forward to repair as they all had the same components plus tendencies, then as the years have passed by plus HVAC technology has improved so much the task isn’t nearly as straight-forward as it used to be! While I have made sure to stay with the times plus learn how to handle all of the newer models of air conditioner units, not everyone can say the same, but over the last ten years I have had to let go of several undoubtedly hard working HVAC repair techs not because they weren’t hard workers, they simply weren’t able to handle dealing with modern air conditioner units.
I recognize you could stay that you can’t teach seasoned pets modern tricks. I understand where they were coming from however, It’s constantly a bit aggravating to see the work you have had changed so much over such a short period of time, however as a homeowner I can say that I guess it is all for the better; More complicated air conditioner units means that only the cream of the crop will be left in terms of HVAC repair techs which will not only lead to less complications picking the right 1s for homeowners, however lead to more purchasers for fellow HVAC companies… HVAC technology will constantly advance no matter what, plus there is nothing any there repair techs can do other than stay up with the times.
